Getting ready to upgrade from the headunit power to a 4-channel amp and a mono block amp. Each of the amps has a fuse built in. My question is besides the power wire fuse required near the battery do I still need (or want) a fused distribution block if the amps are fused? According the the gurus at Crutchfield the fused block is not necessary if the amp or amps are fused.
From their web site:

Q: Do I need a separate fuse block too?
A: A safe system will have the right fuses installed at each amplifier and also on the power cable by the battery. But if you've ever taken a peek at some competition-style car audio systems, you may have noticed fuses at a third location — in a fuse block by the components. Sure this hardware looks good, but is it necessary?
Unless your amplifiers are among the few that don't come with fuses installed, the answer is no. The reason you see these "redundant" fuses is that in the early days of car audio competition, amplifiers frequently didn't include their own fuses, or if they did, often hid them behind panels that were hard to get to, especially in the heat of competition.
Today, the use of such fuse blocks is largely a matter of style. But that's OK — looking cool definitely counts. In the world of car audio, it's a close third, right behind being safe and sounding great.

Now I trust you guys more then them so do I need or want the fuse block or just a power distribution block?

they are correct as long as power wire and amps are fused. i use a fused block because my avionixx amp although brand new does nto have an on board fuse. but before this amp i did not use a fused block. if it makes you feel safer feel free to but it is not nessicary.

Agreed, if amps are fused, then there is really no need for a fuse D-block.
When installing amps or servicing them.. just pull the fuse at the battery, do you work and then reinstall the fuse.
